I think the problem is that U of Phoenix, Kaplan, etc. are not traditional not-for-profit academic institutions. They are businesses. I think that although University of Phoenix is actually regionally accredited, it is still thought of as academically suspect.
I took A&P I and II online at Northern VA community college. The transcript does not indicate anything about being an online course. From what I've been able to tell, the courses seem to be acceptable at all of nursing schools in the DC area. I would just make sure that the courses are taken through a regular, regionally accredited, not-for-profit school
I'm thinking of applying to a few different school and starting to take pre-reqs and co-reqs. One wants Psy I and II, another wants Developmental Psy, and another wants Abnormal Psy. Frustrating.
